Abstract
The number of artificial sources of ground-borne vibrations is escalating with an increase in the construction activities of rail and road traffic systems. These ground-borne vibrations may disturb the stability of nearby old structures. The geo-mechanical problems associated with ground-borne vibrations can be solved by analyzing the soil–structure interaction using various numerical methods. Theoretical evaluation and mitigation of ground-borne vibration in sub-structural systems has been explained in the present study with the help of practical application. First, the open and infill trench methods of vibration mitigation and their efficiency are discussed. Then the assessment of blast-induced vibrations soil parameters and the response of the railway track system under cyclic loading are briefly reviewed. An emphasis has been given on evaluating the effect of vibrations induced by construction activities such as tunneling, blasting, piling, on heritage structures in the nearby area. The impact of proposed tunneling operations on adjacent heritage structures has been assessed and explained through a case study.
